Tom Petty & the Heartbreakers will play a second small-scale show this weekend at a 500-seat theater in Northridge as a benefit for public radio station KCSN-FM (88.5).

“The reaction has been insane,” KCSN program director Sky Daniels told Pop & Hiss over the weekend, referring to the initial Oct. 29 show Petty and the band announced last week as a fundraiser during the station’s fall pledge drive. Pairs of tickets were being offered to callers who pledged $150 or more during random “cue to call” announcements on the air. “30 callers for every pair [from] all over the globe," Daniels wrote in an e-mail. "People are pledging from Norway, Canada, Boston, Orlando, etc. -- all willing to fly here to see Tom in this small setting.”

Update Oct. 25 at 12:37 p.m: An earlier version of this post gave the date of the first Tom Petty show as Oct. 28. It is Saturday, Oct. 29.

The second show will take place Oct. 30 in the 500-seat Performance Theater at Cal State Northridge. Tickets for the second show were largely distributed over the weekend during additional “cue to call” announcements, but orchestra pit tickets will continue to be available via an auction running through 5 p.m. Tuesday on the station’s website.

“For them to selflessly want to perform this show speaks volumes for their love of music, and their willingness to support KCSN's effort to build a radio station devoted to breaking new artists, supporting local artists and respecting great legacy artists,” Daniels said in a statement. “Tom and the Heartbreakers recognized the overwhelming demand and wanted to give more fans a chance to see them in this intimate hall, as well as help KCSN and public radio."

In addition to the Petty concerts, KCSN's pledge drive is auctioning off autographed guitars signed by superstar acts including U2, Mick Jagger, Coldplay, Bob Seger, Sheryl Crow and Melissa Etheridge.
